Wheat varieties and leaf rust samples of Hebei province were collected in 1982 and study of interaction between host and pathogen was made in 1983. The results expressed by virulence frequency showed that this method of investigation provided directly the information of the interrelationship between the wheat varieties and the rust fungus .

我科研组采取毒力频率来研究河北省小麦品种和河北省叶锈菌的相互作用，我们认为：这种研究方法能直接反应品种与菌株之间相互作用的情况，对生产者和抗病育种工作者提供的信息，要比小麦叶锈菌小种鉴定提供的以编号对小种命名的小种名单要有用得多。

The different operation methods should be selected according to the different sides and sizes of the tumor;the parotid gland pleomophic adenoma in superficial lobe with clear limit and small size shouid be treated by local regional excision to reduce facial deformity and various kinds of complications,but those with too big size and vague limit should be done by traditional superficial lobe parotidectomy.

应根据肿瘤的部位及大小选择不同的术式，对界限清楚、体积较小的腮腺浅叶多形性腺瘤应尽量采用腮腺区域性切除术，预防面部凹陷畸形，减少并发症；对过大或边界不清的肿瘤仍宜采用传统腮腺浅叶切除术，以减少复发。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.

DNA C值与被子植物入侵性密切相关，为考察应用DNA C值评估被子植物入侵性的可靠性和局限性，我们统计分析了全世界范围内3676种被子植物的DNA 1C值（配子未发生DNA复制时的染色体DNA含量）及基因组大小（单个染色体组的DNA 含量），结果表明：1）DNA 1C值和基因组大小在被子植物不同类群中差异极大，例如在草本植物中显著高于木本植物，单子叶植物显著高于双子叶植物，多年生植物显著高于非多年生植物；2）两项指标都与被子植物入侵性显著负相关，尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中，然而在木本植物、豆科植物中其与植物入侵性无显著关系。

Results The main imaging of adult polycystic kidney disease signs: abdominal plain film (45 cases) showed renal shadow was lobulated increase; cystic wall calcification (14 cases); polycystic kidney disease and renal milk of calcium (8 cases); pelvis angiography (61 cases), the performance of the renal pelvis, renal calices separated, distorted, elongated; retroperitoneal inflatable angiography (6 cases): Performance increases of renal kidney shadow Shadow and the relationship between the neighboring organs, its boundaries clear and identified; CT scan (30 cases): the performance of the majority of the size of the renal low-density areas, ranging from thin-walled circular; B-mode ultrasonography (47 cases) showed a circular echo-free renal multiple classes of liquid dark area .

结果 成人多囊肾的主要影像学征象：腹部平片(45 例)显示肾影呈分叶状增大；囊壁钙化(14例)；多囊肾合并肾钙乳(8例)；肾盂造影(61例)，表现为肾盂、肾盏相互分离、变形、拉长；腹膜后充气造影(6例)：表现为肾影增大肾影与邻近器官之间的关系，其界限清晰可辨；CT扫描(30例)：表现为肾内多数大小不等的薄壁圆形低密度区；B型超声(47例)表现为肾内多个类圆形无回声的液性暗区。结论影像学检查有助于提高多囊肾的诊断的准确性。

In cross-sectioned root form 2 middle bark layer next Internal bark layer especial structure of regularly array; epidermis cell of stems and leaves have developed thickened epiderm, leaves epidermis covers hair, it formed developed vascular bundles.(4)Chromosomes of Agropyron cristatum is tetraploid .

根横切面上形成了在紧靠内皮层的两层中皮层细胞有规则整齐排列成两环的特殊结构；茎和叶表皮细胞均具有发达的角质层，叶表皮多密被毛，其形成了发达的维管束及维管束鞘。

CT characteristics: malignant GISTs mainly qualified as large size, inequable density, necrosis and cystoid changes in the center, unsmoothing and lobulated border lines, inequable reinforcement after enhanced CT scanning.

CT特征：恶性度较高的胃肠间质瘤CT表现为：肿块相对较大，密度不均，肿瘤中央坏死及囊变多见；肿瘤边缘多不光整，可呈分叶状。

Abstract］ Objective The significance and reason of multi-lines of interlobar fissure revealing on MIP reconstruction imaging in multi-row CT scanning was approached.

Previous studies show different interneuron changes in different models of epilepsy, which are focused on the onset of epilepsy, but not the onset of the spontaneous recurrent seizures.

在不同癫痫模型和患者海马观察含PV、CR、CB中间神经元数量变化的报道已有较多，但既往的研究着重于颞叶癫痫的始发过程上，而对颞叶癫痫发生后向自发性复发性发作演变过程中这三种中间神经元变化的研究较少。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
